WIPEFS(8) MAINTENANCE COMMANDS WIPEFS(8)NAME
wipefs - wipe a filesystem signature from a device
SYNOPSIS
wipefs [-ahnp] [-o offset] device
DESCRIPTION
wipefs allows to erase filesystem or raid signatures (magic strings)
from the device to make the filesystem invisible for libblkid. wipefs
does not erase the whole filesystem or any other data from the device.
When used without options -a or -o, it lists all visible filesystems
and offsets of their signatures.
OPTIONS-a, --all
Erase all available signatures.
-h, --help
Print help and exit.
-n, --no-act
Causes everything to be done except for the write() call.
-o, --offset offset
Specifies location (in bytes) of the signature which should be
erased from the device. The offset number may include a "0x"
prefix, and then the number will be read as a hex value. It is
possible to specify multiple -o options.
The offset argument may be followed by binary (2^N) suffixes
KiB, MiB, GiB, TiB, PiB and EiB (the "iB" is optional, e.g. "K"
has the same meaning as "KiB") or decimal (10^N) suffixes KB,
MB, GB, PB and EB.
-p, --parsable
Print out in parsable instead of printable format. Encode all
potentially unsafe characters of a string to the corresponding
hex value prefixed by '\x'.
